CO₂ Flow Metering Technologies

The main objective of this study is to raise awareness of the relevance, state of the art, challenges and opportunities of flow metering for carbon capture, utilisation and storage (CCUS). Flow metering of CO₂ streams will be critical in supporting trade, protecting consumers, ensuring confidence, facilitating taxation, and meeting CO₂ reduction goals and treaty obligations. To date, standardized methods for accurately measuring CO₂ — ensuring traceability and accountability—have not yet been developed. This presents challenges for process control, leak detection, and verification of emissions reporting.
